Abstract

The invention discloses a baking map generation method and device, a baking map use method and device, equipment and a medium, and belongs to the technical field of computers. The method comprises: determining view angle division information of m first view angle ranges and n second view angle ranges of a camera model, wherein the first view angle ranges are not divided into view angle sub-ranges, and the second view angle ranges are divided into a plurality of view angle sub-ranges; obtaining a first visual angle map of the three-dimensional virtual article in a first visual angle range through a camera model, and obtaining m first visual angle maps; obtaining a second visual angle map of the three-dimensional virtual object in the visual angle sub-range through the camera model, and obtaining n groups of sub-visual angle maps; performing down-sampling processing on the n groups of sub-view-angle maps to obtain n groups of second view-angle maps; and respectively mapping and drawing the m first view angle maps and the n groups of second view angle maps to different map areas of the baking map according to the view angle division information. According to the method, the baking chartlet can accommodate more visual angle chartlets under the condition that the size is not changed.

Description

technical field

[0001] The present application relates to the field of computer technology, and in particular to a method, device, equipment and medium for generating and using baked maps. Background technique

[0002] A camera model is set in the 3D virtual space, and the camera model shoots 3D virtual items located in the 3D virtual space, and the terminal renders the virtual environment picture captured by the camera model to a screen of the terminal for display.

[0003] In order to reduce the amount of calculation in the rendering process, the baked texture of the 3D virtual item is pre-made and stored, and the baked texture includes texture images of the 3D virtual item under multiple different viewing angles. The terminal loads the baked textures in the memory in advance. When the camera model shoots a 3D virtual item (or a patch disguised as a 3D virtual item), the terminal obtains the current shooting angle of the camera model, and selects the corresponding image fr...
